Economic Left/Right: -6.75
Social Libertarian/Authoritarian: -4.82

I think I'm a little more socially liberal than that. Maybe. Also, I have a problem with this question.

"A significant advantage of a one-party state is that it avoids all the arguments that delay progress in a democratic political system"

This is obviously a true statement. There really is no matter of opinion involved. A one party state will avoid the arguments that delay progress in a democracy. Silly question.
